The president announced trade deal with India today in his 10-day trip in Asia. "There is no reason this nation can't be one of our top trading partners," the president said. To that end he said the U.S. would put forward a package of reforms on export controls that resulted from past administrations' concerns about India's nuclear industry. " USA don't sell Uranium to India, it goes somewhere to buy anyway.
India is forced to use Uranium since development has always run into difficulties and international Nuclear power countries do not want India use Thorium due to concern over weapons proliferation risk of U-233 (if it could be separated on its own).
"Much development work is still required before the thorium fuel cycle can be commercialised, and the effort required seems unlikely while (or where) abundant uranium is available. In this respect, recent international moves to bring India into the ambit of international trade might result in the country ceasing to persist with the thorium cycle, as it now has ready access to traded uranium and conventional reactor designs."
